How To Solve For Shaded Area

Answers

Answer 1

Answer:

(a)  12.96 ft²

(b)  21.5 in²

Step-by-step explanation:

(a) For the first diagram

Area of the shaded region (A) = Area of Tripezium- area of circle

A = [1/2(a+b)h]-[πr²]............... Equation 1

Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.

From the diagram,

Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.

Constant: π = 3.14

Substitute these values into equation 1

A = [12(15+6)/2]-(3.14×6²)

A = 126-113.04

A = 12.96 ft²

(b) For the second diagram,

Area of the shaded region (A') = Area of square- area of circle

A' = (L²)-(πr²)............. Equation 2

Where L = lenght of one side of the square, r = radius of the circle

From the diagram,

Given: L = 2r = (2×5) = 10 in, r = 5 in

Substitute these values into equation 2

A' = (10²)-(3.14×5²)

A' = 100-78.5

A = 21.5 in²

Rewrite the expression by using the distributive property and collecting like terms 1/5(5x-15)-2x

Answers

Answer:

-x-3

Step-by-step explanation:

First, you need to distribute the 1/5 to both the term 5x and the term -15, which requires multiplication. This gives you 1x-3. The -2x can then be added on to this equation, which gives you 1x-3-2x. Combining the like terms of 1x and -2x gives you -x. The entire expression is then -x-3.

Answers

Answer:

x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)

Step-by-step explanation:

Given quadratic equation:

16x² - 20x - 6 = 0

Quadratic formula is given by:

x = -b² ± √b² - 4(a)(c) / 2a

16x² - 20x - 6 = 0

From the equation,

a = 16

b = -20

c = -6

x = -b² ± √b² - 4(a)(c) / 2a

x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)

x = -(400) ± √(400) - (-384) / 32

x = -400 ± √400 + 384 / 32

x = -400 ± √784 / 32

x = -400 ± 28 / 32

x = (-400 + 28) / 32 or x = (-400 - 28) / 32

On a child’s birth, a deposit of $2000 was put into an account that pays 5% interest compounded annually. How much is in the account after 18 years?

Answers

Answer: $4,813.24

Step-by-step explanation:

This requires the use of a future value formula because we are to find the value of an amount in future after compounding it over a certain period.

Future Value = Amount * (1 + rate) ^ number of years

= 2,000 * ( 1 + 5%)¹⁸

= $4,813.24

In 18 years, the $2,000 would have increased to $4,813.24.

How to get the answer of 2/5 X -3/7 - 1/14 - 3/7 X 3/5 using distributive property of multiplication?

Answers

Answer:

The answer to the given question is - ¹/₂

Step-by-step explanation:

Given;

[tex]\frac{2}{5} \times -\frac{3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}[/tex]

Before we apply the distributive property, perform the multiplication operation.

[tex](\frac{2}{5} \times -\frac{3}{7}) - \frac{1}{14} - (\frac{3}{7} \times \frac{3}{5} )\\\\\frac{-6}{35} - \frac{1}{14} - \frac{9}{35}[/tex]

Now, apply the distributive property, to obtain the final answer,

In distributive property, the following rule is applied;

ax + ay = a(x + y)

[tex]\frac{-6}{35} - \frac{1}{14} - \frac{9}{35} = \frac{-1}{7} (\frac{6}{5} + \frac{1}{2} + \frac{9}{5} )= \frac{-1}{7} (\frac{12 + 5+ 18}{10} )= \frac{-1}{7} (\frac{35}{10} ) = \frac{-35}{70} = \frac{-1}{2}[/tex]

Therefore, the answer to the given question is - ¹/₂

Answers

Answer:

step 1

Step-by-step explanation:

Given

(x - 2)(3x + 4) ← apply distributive property

= (x - 2)(3x) + (x - 2)(4)

                        ↑ error is here , she put (x + 2)

In this exercise we have to use the knowledge of the distributive property, so In alternative 1 she made the mistake.

What is distributive property example?

The distributive property is used when a number is multiplying an addition or subtraction. Simply multiply each term separately and add or subtract the result. We distribute the multiplication of the 2, to the 8 and to the 3.

Proving the mistake:

[tex](x - 2)(3x + 4) \\= (X)(3x) + (-2)(3x) + (x)(4) + (2)(4)\\and not\\(x-2)(3x) + (x + 2)(4)[/tex]

Answers

Answer:

Order from greatest to least: 10.5, [tex]3\pi +1[/tex], [tex]\sqrt{105}[/tex]

Step-by-step explanation:

step 1 simplify each number

3π + 1  = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

[tex]\sqrt{105} =10.2469507[/tex]

*round to the nearest tenth*

[tex]\sqrt{105} =10.2[/tex]

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = [tex]\sqrt{105}[/tex]

Your answer is

10.5 , 3[tex]\pi[/tex] + 1, [tex]\sqrt{105}[/tex]
